he objects .of the invention are to avoid dancers inside tette wie ef. Windows; to make reversible windows a aptable to the colder climates by closing up joints and thereby stopping the penetration of the cold air; to insure reliable fastening in the sash guides; and generally to provide an efficient and economical reversible Window.

In the drawings, Figure 1 is a perspective view of the window showing the sashes in their normal positions.

Figure 2 is a perspectiveyiew of the window showing the sashes reversed for cleaning purposes.

Figure 3 is a cross sectional view'on the line 3--3 in Figure 2.

Figure 4 is a detail of the latch movable strip.

Figure 5 is a perspect-ive detail of a sash and sash runner. Y

Figure 6 is an enlarged detail showing an inserted weather strip.

Like numerals of reference indicate correspondingparts in the various figures.

Referring to the drawings, the window frame 10 has the inner and outer longitudinal grooves 11 and 12 at one side, the grooves being partially closed in from either side by the metal flanges 13, 13 and 14, 14, which are secured by means of screws to the inner sides of the walls `16 of the side walls or strips of the grooves 11 and 12.

The upper and lower window sashes 35 and 36 respectively are slidable in the longitudinal grooves 11 and 12 and adapted to he pulled up and down and held by means of the sash cables 18 and 19 trained over the pulleys 20 and 21 leading into the weight box 22.

The window sashes are carried on the one side by the sliding brackets 23 and 24 having the runners 25 and 26 sliding in the longitudinal grooves 11 and 12 respectively and retained therein by the anges 13, 13 and 14, 14, said brackets 23 and 24 being metal bound at their inner sides as shown by the metal strip coverings 27 and 28 respectively.

in the rethe window panes from the interior of the room and thus avoid the necessity of going outside with its consequent dangers.

The free ends of the window sashes and 36 are normally retained in the outer and inner sliding grooves 38 and 39 respectively.

The wall of theouter groove is cut away to form the removable sash strip 40 and this removable sash strip 40 has a pin 41 extending from its lower end and inserted in t-he sill 42 within the hole 43 and towards its upper end the said strip 40 is held to the frane by the spring latch 44 which snaps into the catch 45 of the frame, thus retaining the sash in its place under ordinary conditions, the removable strip 40 is recessed in the frame 10 for its complete length, the recess 46 in the frame containing the catch 45 and extends for the whole length of the strip 4() below the permanent strip 47 of which the strip 40 forms a continuation of the grooved wall.

The inside wall ofthe inner sash groove is also divided into permanent and hinged sash strips 48 and 49 respectively, the removable strip 49 being secured to the Window frame 1() by the hinges 50 and 51 and meeting the strip 48in the bevelled joint 52. The strip 49 closes in on the frame 10 against the sash 36 and inside the aligning snap fastener 53 is secured to the strip 49 and to the window frame respectively in regard to itstwo members the inner member having an aligning pin 54 to insure a continuance ofthe strip 49 of its close fit to the window sash 36.

In the operation of this window the lower sash 'its into the sill, that is to say, closes down behind the inside ledge, which is customary construction, but it means that it has to be lifted slightly to escape the ledge of the sill, the strip 49 is then swung on its hinges which leaves the sash 36 freeto be opened inwardly for cleaning purposes. The strip 40 isthen removed by pressing on the spring'latch and the sash 35 drawn downwardly until it escapes the lower end of the permanent section `of Vtheirniddle Wall separating the sash grooves. This upper sash then can be opened for cleaning purposes the saine as the lower sash.

It really must be emphasized herein the frame having sash grooves in opposite sides and metal strips secured to the `frame partiaL` ly closing in the grooves and forming guides, a sash having a vertical rabbet at one side, a wooden bracket forming `a sash support and having nietal facing strips forming vertical binding,r pieces runninr on said metal strips in the window frame and having a rabbet registering with the vertical rabbet in said sash and completing a rabbct joint in the closed position and converging at the inner side to a neck, a runner forming a part of said wooden bracket and sliding; inone of the window grooves and :rhinged strip se`c tion having;v fasteners thereon locking the sash frame in tho other oi said window grooves.
